FAQ:1. Conical end of set screw (pointed): generally used in places that are not long removed after installation, among which
1) Tip - suitable for parts with less hardness;
2) Concave end - suitable for parts with greater hardness;
2. Cone end of the set screw (no point): It is necessary to make a hole on the top tightening surface of the part first, so that the cone surface is pressed on the edge of the hole to enhance the ability to transmit loads;
3. Flat end round tip of the set screw: it is mostly used in the connection of the often adjusted position, and the load is small. The flat end - large contact area, can be used for parts with high top hardness, and the top tightening surface should be a flat round tip - The surface of the part needs to have U-shaped grooves, V-shaped grooves or circular sockets, etc.;
4. Cylindrical end of the set screw: used for frequent adjustment, or to fix the parts mounted on the pipe shaft (thin-walled parts), the cylindrical end enters the large hole on the pipe shaft, and the end can be transmitted by shearing action For larger loads, there should be a device to prevent loosening when using this type of screw.
